No module named 'lsb_release' after install Python 3.6.3 from source

 

Solution:

sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py

Explain:

We can see in /usr/bin/lsb_release

#!/usr/bin/python3 -Es

import lsb_release

The key step is import lsb_release, but the problem is Python 3.6 doesn't have this module.

So, you must have overrided python3 from python3.5 to python3.6. That's why your lsb_release is broken.

To verify it, we can see in python3.6:

➜  ~ python3.6 
Python 3.6.4 (default, Feb  6 2018, 16:57:12) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'lsb_release'

then in python3.5:

➜  ~ python3.5
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
>>> lsb_release.__file__
'/usr/lib/python3/dist-packages/lsb_release.py'

where is this file:

➜  ~ ll /usr/lib/python3/dist-packages/lsb_release.py
lrwxrwxrwx 1 root root 38 Jul   7  2016 /usr/lib/python3/dist-packages/lsb_release.py -> ../../../share/pyshared/lsb_release.py

So, this module lsb_release exist in python3.5 but not exist in python3.6. And We find it eventually!

Now let's fix it through add a link to the original lsb_release.py file!

It works for me!
